Reinstall ShoWorks but save the downloaded file instead of running first, then right-click on the downloaded file and choose 'Run As Administrator'.

Then if the problem is still not resolved, start ShoWorks by right-clicking on the ShoWorks icon and choosing 'Run As Administrator'. Note: if this process is needed, you can permenantly change the icon to always start as an Administrator by right-clicking on the ShoWorks icon and choosing 'Properties' then 'Compatibility' and placing a check in the box 'Run this program as an administrator'.
